Well, as you can see from the title, I'm having issues with SVN and Putty. It won't let me checkout and each time I try to do it, it outputs this message: "server unexpectedly closed network connection".

First time when I wanted to check out from this location, it prompted me for login info, login info was incorrect, and after third time and each after that it led me to that error, so I don't even get the prompts anymore.

I thought that this may be a server-side issue, where they blocked my ip address, but that is not the case.
